My graphtech program is looking crazy with green lines in the background. I can use the interface but everything on the canvas is jittery and I can't open older files.
I have tried restarting the program, the pc and reinstalling the program a bunch of times. Nothing has helped. My pc has two graphic cards and I have also tried to deactivate one of them.
Any idea what I could try next? Are there any other programs I could use that has the same functions?
